Design/methodology/approach - This is exemplified by an application scenario in healthcare that was developed in the context of the OpSIT project in Germany. A clearly outlined three-layer architecture, in the sense of Internet of Things, is presented. It provides the basis for integrating a broad range of sensors into smart healthcare infrastructure. More specifically, by making use of short-range communication sensors (sensing layer), gateways which implement data transmission and low-level computation (fog layer) and cloud computing for processing the data (application layer). Findings - A technical in-depth analysis of the first two layers of the infrastructure is given to provereliability and to determine the communication quality and availability in real-world scenarios. Furthermore, two example use-cases that directly apply to a healthcare environment are examined,concluding with the feasibility of the presented approach. Practical implications - Finally, the next research steps, oriented towards the semantic tagging and classification of data received from sensors, and the usage of advanced artificial intelligence-based algorithms on this information to produce useful knowledge, are described together with the derived social benefits. Originality/value - The work presents an innovative, extensible and scalable system, proven to be useful in healthcare environments.}, language = {en} } @inproceedings{GhulammMuhammadSalimiJaedickeetal.2015, author = {Ghulamm Muhammad, Sarfaraz and Salimi, Meysam and Jaedicke, Corvin and Stantchev, Vladimir and Prieto-Gonz{\´a}lez, Lisardo and Tamm, Gerrit}, title = {Cloud Computing: an Enabler in the Modern Labour Market}, series = {Labour in the 21st Century}, booktitle = {Labour in the 21st Century}, publisher = {Cambridge Scholars Publishing}, address = {Newcastle upon Tyne}, isbn = {978-1-4438-1707-3}, pages = {66 -- 77}, year = {2015}, abstract = {Modern day labour market is influenced by different factors, mainly by ambitious investment in latest machinery, office automation software systems and computer-based solutions. Utilization of computer has benefited the employment market on vast scale, depending on the requirements of a particular business, its size and financial capabilities, and the intention to use. Furthermore, unparalleled technologies, such as cloud computing and smart technologies has directly affected demand for modern day labour. Nowadays, the utility model of cloud computing made it more popular and a favourite choice for the institutes to free up their internal resources and also reduce the number of administrative staff needed to maintain it. With certain kinds of offerings, institutes operating at small scales are also benefitting, which was almost impossible only a decade ago. Given that, the successful utilization of cloud computing remains a topic of extra ordinary importance among the scholars, experts, interested groups and several other institutions, and is defined in different ways according to their particular understanding and usage.
